How Long Does a Furnace Replacement Take?
A straight furnace swap is usually done in one day. Venting changes, a chimney liner, gas line or duct work, and the permit inspection add time. What to expect.

Swapping out a furnace in Mound runs $4,500–$9,500 installed with us. In converted cabins, the new unit is often a horizontal or compact model that has to fit a crawlspace or closet, and we measure before pricing. For rebates, Mound's gas utility is CenterPoint Energy.
Replacing a furnace in a converted Mound cabin starts with the space. A closet furnace has to match the opening, the door clearance and the route its flue or PVC takes outside. A crawlspace unit is usually a horizontal model that has to fit through the access hatch and sit above any water. Condensing furnaces also need a drain route that won't freeze in a cold crawl. When the crawlspace can be sealed and insulated so the ducts sit inside the heated envelope, a new furnace works well there. When it can't, ductless heat pumps may be the better investment.
On tight lake lots, a side-wall vent has to keep its clearances from windows, doors and the property line, which can decide where the furnace goes. Mound's postwar ramblers and split-levels are standard basement swaps. CenterPoint Energy supplies the gas, and its heating system rebates cover qualifying high-efficiency furnaces. The mechanical permit is part of our quote.

An installed furnace from us runs about $4,500–$9,500 in Mound: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Mound as in every town we serve. See the furnace replacement cost guide.
Mound's gas comes from CenterPoint Energy and its electricity from Xcel Energy. For the baseboard-heated and converted-cabin homes, Xcel's rebates are the ones that count: they cover air-source heat pumps and ductless mini-splits, and many measures need an Xcel-registered contractor, so ask first. Xcel also offers Heating Upgrade Rebates for electric space heating. CenterPoint's heating rebates cover high-efficiency gas furnaces, boilers and thermostats, installed by the dealer you choose. Rebate programs change every year, so check the utility's current terms before you buy.

Often, but we measure before we price. Horizontal furnaces come in different cabinet widths and lengths, and some are compact enough to pass through a standard access opening. If the hatch is too small, it may need enlarging, which goes into the written quote. We also plan how the old furnace comes out and where the new condensate drain runs, so install day holds no surprises.
Sometimes, but it's rarely the simplest route. A wall furnace heats from one spot, and replacing it with a central furnace means adding ductwork, which is hard in a cabin with no basement and a shallow crawl. Ductless heat pumps usually fit these houses better: a head or two covers the main rooms, and they cool in summer too. With us, ductless systems run $4,200–$12,500 depending on the number of heads.
